Great quiet pumps, but need to be upgraded for use with ApexBy Vincenton 3/30/2015

The reviews here say it all. Great pumps! However if you are going to use this on an APEX you are limited to 2 ports (4/8). If you want to use it on the other ports you will want to get one of these or similar for each pump (Woods 4325C Single Outlet Power Adapter Plug) BRS I suggest you start selling these....

Very impressed with the overall construction. Nothing best on this price range, I'm currently using the unit for Mg dosing. Would recommend it without hesitation

Ordered two and have not looked back as far as dosing. I use with the BRS additives and my corals could not be any happier!

After years (literally) of dosing 2-part by hand, I bought two of these pumps during the Black Friday 2014 sale. Due to the tight space in my stand/sump area, installation took a bit of thought and time. But once up and running, they are, as my teenage daughter would say, "just sick." I control them with my Reefkeeper Lite's multi-timer function and the levels are always spot on. And now I don't have to train my neighbors in the fine art of dosing 2-part!

Great!By Jeffon 1/11/2015

I bought 2 and have them controlled by my reefkeeper. Easily dose 2.2ml for 24 hours and keeps everything stable.

Great Dosing Pump for KalkwasserBy Jimon 1/9/2015

We're using this pump for Kalkwasser dosing from reservoir in basement to display tank upstairs. It works fine, and doses a very slow drip, so can run all night to keep the pH stable.

I had a calcium reactor running on my sps dominant tank for 8 months but just did not like the inability to keep track of all the elements being dosed. Switched over to brs two part with Red Sea additives and couldn't be happier. I have sent in my water to be tested by triton through uniquecorals and nothing but green

Great little pumpBy 200 Gallon Reeferon 12/24/2014

Got this pump to dose my 2-part alkalinity solution. Provides a nice slow steady drip and is dead silent. The first time I turned it on I couldn't tell it was running until I saw it slowly turning. Comes with input and output tubing and was super easy to set up. I'm using my Reef Keeper as a timer and it's keeping my alkalinity right where I want it. I would definitely recommend this pump for dosing.

simple, straight forward, use with a apex controller and you're set

Using two of these reliable unitsBy Marcon 12/16/2014

Been using two of these for dosing calcium and alkalinity for 6 months now. The units are solid and reliable. I'm using the hamilton digital timers to control the dosing.

Just added a third pump to dose vodka. I've had 2 others for over a year with no problems

Exactly what I needed.By Matton 12/9/2014

Easy to set-up. Easy to calibrate. Works great with controllers for consistent dosing. I used 30 minutes to calibrate my pumps instead of the recommended 10 and I think I got a bit more accuracy with my dosing. Both were very close to the 1.1mL per minute rate, but not spot on so don't forget to calibrate! Very quiet operation and my tank is already more stable.
